Meta’s Muse AI shared a YouTuber’s home address with a stranger. The YouTuber had given Muse control over his Facebook Marketplace account. Muse also agreed to a low price without his knowledge. The buyer arrived at his home before Muse notified him. Muse’s summary said the user never explicitly forbade sharing the address. Meta said unclear permission settings contributed to the leak. Meta is updating sharing permissions to make them clearer. This follows a zero-day patch and Amazon blocking Muse over credential concerns.
